EPS FLUTE FILL COMBO
1 of 2 www.duro-last.com 800-248-0280
Description:
Duro-Guard ® EPS Flute Fill Combo is a premium
insulation consisting of a superior closed-cell,
lightweight and resilient expanded polystyrene (EPS).
It meets or exceeds the requirements of ASTM C
578, Standard Specification for Rigid, Cellular
Polystyrene Thermal Insulation.
EPS Flute Fill Combo can be cut to fit virtually all
types of steel deck and metal roof profiles, thus
elimimating any need for a separate flute filler. It can
be ordered with a polyester facer or fire rated (FR)
coated-glass fiber mat facer.
Benefits:
 FR facer helps to achieve UL class A roof
assembly over noncombustible decks. Refer to
UL listings for maximum incline.
 Both facer types eliminate the need for a
slip sheet.
 Shiplap joints help prevent thermal bridging.
 High thermal efficiency and maximum durability.
 Reduces inter-ply adhesive and saves labor.
 Provides long-term thermal insulation value.
 Does not contain CFCs or HCFCs.
 Superior moisture resistance.
 100% recyclable.
 Available in three densities per ASTM C 578:
o Type I, 1.00 pcf.
o Type VIII, 1.25 pcf.
o Type II, 1.50 pcf.
 Refer to Table 2 for physical properties.
Recommended Uses:
 Mechanically attached Duro-Last ® roof systems.
 Duro-Bond ® roof systems.
 Metal retrofit roof systems.
Refer to the appropriate installation specification for
the above uses.

Installation:
 Duro-Guard EPS Flute Fill Combo may be
used directly under the Duro-Last membrane
with either polyester or FR facer. Care should
be taken to ensure that “bare” EPS is never in
direct contact with the membrane. Refer to
the appropriate Duro-Last specification for
slip sheet and cover board requirements.
 Panels must be kept dry before, during and after
installation. Install only as much insulation as can
be covered the same day with completed roofing.
